I was looking at the HC website and saw this about the esc.
"WARNING: For some large motors, you must use ''High'' timing mode. Failure to do so will result in a burnt esc."
How is your timing set for the ESC? It may, or may not be the problem, but at least it's a start.
Also, the information on the 100 amp ESC said it was only good up to 6 cells. Do you think it will be able to handle the two extra cells if you keep the amps low enough?
